PCI: mobiveil: Allow mobiveil_host_init() to be used to re-init host

Browse Source 
Allow the mobiveil_host_init() function to be used to re-init
host controller's PAB and GPEX CSR register block, since the NXP
integrated Mobiveil IP has to reset and then re-init the PAB
and GPEX CSR registers upon hot-reset.
